Multithreading exception

[burkovsky]

Hi,

I have a reports which renders perfectly on single thread.
If I generate many of them in several threads it crashes in
ExportDocument(StiExportFormat.Pdf, memoryStream)

System.InvalidOperationException was unhandled

VisualStudio also shows:
If you are using the Graphics object after the GetHdc method, call the ReleaseHdc method.
This will release the context handle obtained by a previous call to the GetHdc method of the Graphics object.
